SULPHURIG ACID-DlSTRlBUTlNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 378,289, dated February 21, 1888.

Application [lied March 1, 1887.

T0 aZZ whom it may concern.-

Be it known that I, Fnnncrs W. CHAIPELL, of the city of Baltimore and State of Maryland, have invented certain Improvements in Distributing, Apparatus to be Used in the Manufacture of Sulphuric Acid, of which the following is a specification.

This invention relates to certain improvements in an apparatus to be used in connection with either a Glover or a Gay-Lussac tower, but which is particularly adapted for employment in connection with an improved tower described in application No. 226,919, pending herewith.

The object of the said invention is to divide the acid delivered to the tower into alarge number of small streams, each one of which is conducted separately to a cup connected to the top ofthe tower and in communication with its interior.

The said invention, briefly stated, consists of a base supported in any suitable manner over the top of the tower, to the upper side of which are attached rings, which, in connection with the portion of the base situated between them, form an annular pan. This annular pan is divided into annmber of compartments by means of diagonallyplaced adjustable partitions solidly attached to the base and the lower part of the rings, and from each compartment extends a pipe, whereby its contents are conducted to a cup connected with the top of the tower. Over the adj ustablc partitions, and resting on their upper edges, and situated about equidistant between the rings, is placed a hoop or band of lead. In the center of the base is placed a reactionary wheel, which re ceivcs the acid to be distributed at its axis and dischargcsit at its arms to the hoop erected on the edges of the partitions. In the center of the base situated a well or reservoir, which is sunk below and solidly attached at its edge to the base. The purpose of the well is to hold a body of liquid, preferably acid, to float the reactionary wheel, and to receive any acid that may leak to the base and conduct the same to the interior of the tower.

In the further description of the said invention which follows, reference is made to the accompanying drawings, forming a part here of, and in which- Figure I is a vertical section of the improved Serial No. 229,357. (No model.)

apparatus, and Fig. II a hali plan of the same. Fig. III is an enlarged section of a part of the apparatus, as hereinafter described. Figs. IV, V, and VI are similar to those above described, except that the said invention is slightly modified in construction, as herein after specified. Figs. VII and V III illustrate further modifications, as will hereinafter fully appear.

Similar letters of reference indicate similar parts in all the figures.

Referring to Figs. I, II, and III, A is a lead plate, which forms the base of the apparatus. This base rests on an iron plate, G, preferably covered with lead and supported in any suitable manner from the top of the tower, which is not shown.

E E are rings burned or cast to the upper side of the base A, to form the annular pan G. This annular pan is divided by the diagonal partitions c a into the compartments 6 e, a top view of which is shown in Fig. II. At the bottom of each of the compartments 6 is a pipe, I, which leads to a cup (not shown) connected with the top of the tower.

J is a hoop or band erected on the partitions c 0 about equidistant between the rings E. Y

It is necessary to the proper operation of the invention, as hereinafter moreparticularly described, that the partitions c 0 should be at regular distance apart, and while it is a comparatively easy matter to place their lower edges in the proper places, it is difiicult to secure them in an absolutely erect or vertical position. I therefore burn the partitions only to the base and the lower part of the rings, leaving the upper portions of the partitions loose, so that they can be adjusted after they are all in place. (See Fig. III, which is a transverse section of a portion of the base and its attachments on an enlarged scale.)

K is a reactionary wheel, into which the acid to be distributed is fed by means of a funnel, a portion only of which is shown and denoted by z. This reactionary wheel consists of a central or axial pipe, 9', closed at the bottom and provided with the arms k, the ends of which are bent in opposite directions, as in all reactionary wheels. The central pipe of the reactionary wheel is secured in the neck of the flask M, which floats in abody of liquid, preferably acid, in the well or reservoir 0, de-

in the well is governed by the height of the trapped end of the overflow-pipe g, which leads from the bottom of the well 0. This pipe is made of lead and can be bent so as to bring its discharge end to any height required.

Referring to Figs. IV, V, and VI it will be seen that there are two annular pans and two .hoops, and in view of there being two hoops the deliveries from the reactionary wheel are not received on the same horizontal plane.

In Fig. VII the pipes I are shown as situated on radial lines. This arrangement is not considered as satisfactory as that shown in Figs. II and VI, where they are what is termed staggered.

In Fig. VIII the annular pan is shown as in an inclined position, instead of a horizontal one, as in the other figures.

Referring again to Figs. I, II, and III, the operation of the invention is as follows: The apparatus being erected over a tower, as before stated, acid fed to the funnel in the upper end of the central pipe of the reactionary wheel and discharged at the arms causes the wheel to rotate on its axis. The discharged acid is ejected against the hoop J, and is carried as a sheet to the compartments of the annular pan, and thence through the pipes I to the cups of the tower, which, as before stated, are not shown in the drawings, but are illustrated and described in application No. 226,919, before referred to.

The delivery of the acid from the reactionary wheel being constant and the partitions at regular distances apart, the same quantity of acid is introduced into each of the compartments of the annular pan.

I claim as my invention 1. In a sulphuric-acid-distributing apparatus, the combination of an acid-distributor, an inclosing-hoop against which the distributed acid impinges, and receiving-compartments to which the acid flows from the hoop, substantially as and for the purpose specified.

2. Ina sulphuric-aeid-distributing apparatus, the combination of an acid-distributer, an inclosing-hoop against which the distributed acid impinges, arranged, substantially as described, to guide the acid to the receiving-compartments, substantially as and; for the purpose specified.

3. In a sulphuric-aciddistributing apparatus, an acid-distributing wheel adapted to deliver to different horizontal planes, substan- TiYIITy as and for the purpose specified.

4. In a sulphuric-aciddistributing apparatus, a distributing-wheel adapted to deliver to different horizontal planes, combined with two or more receiving-hoops, against which the different streams of acid, as delivered, impinge, substantially as and for the purpose specified.

5. In a sulphuric-aciddistributing apparatus, a circular receiving-pan having partitions with their upper portions adjustable with reference to the said pan, substantially as and for the purpose specified.

6. In a sulphuricacid-distributing appara tus, a circular receiving-pan having partitions diagonal or oblique with reference to radial lines, substantially as and for the purpose specified.

7. In a sulphurio-acid-distributing apparatus, a base-plate for the same, having a central well adapted to hold acid, substantially as and for the purpose specified.

8. In a sulphuric-acid-distributing apparatus, a base for the receiving-pan, having a well in the center thereof adapted to hold acid, with a tight joint where the well connects or unites with the base, substantially as and for the purpose specified.

tral pipe extending into a flask, to which it is secured, substantially as and for the purpose specified.

10. In a sulphuric-aciddistributing appara tus, a base for a receiving-pan, having a well in the center thereof, with a tight joint where it connects with the base, and the said well provided with an adjustable overflow-pipe to regulate and maintain the depth of liquid in the well, substantially as and for the purpose specified.
